Before I get started, just think of your favourite violent game. Got it? Right, now imagine the game with all the violence taken out of it. Would it be as enjoyable? It’s pretty safe to say that the answer would be no. Does this mean (let’s just say you’re agreeing with me for now) that the game in question relies on the violence for it to be entertaining and not through the actual mechanics of the game. I would have to say no, because most games that use gratuitous violence use it in a way to enhance the mechanics of the game. For example, in a game like Gears of War, pulling off a headshot with the sniper rifle from half the map away is satisfying because the mechanics make it a challenging task. The skull explosion and spurt of blood just enhance the feeling you get for pulling it off, just like the ragdoll physics in an action game.
